Cannot open modal dialog containing MS FlexGrid activex control

Question

I am trying to open dialog containing MS FlexGrid ActiveX control using DoModal() from an ActiveX control project(OCX). I added member variable for the FlexGrid control and generated a wrapper class for it through wizard. But the dialog is not showing up after DoModal(). I noticed that the OnInitDialog() is not getting called. The dialog appears if I remove the MS FlexGrid control from the dialog. I have no idea what did I miss.

In the same thread that creates the controls/dialogs make sure that you initialize things with the following calls before creating any of the controls/dialogs.

AfxEnableControlContainer();
CoInitialize();
